【程序媛晒83行代码】人生如码，用代码构造极其简单人生模型的清宵小姐姐...

在中国程序媛中，他们的代码有什么样的魅力，Aone联合云栖社区、饿了么、钉钉、阿里云、天猫、口碑发起首届程序媛比码活动——不秀大长腿，秀高智商；不秀美图照，秀代码图，参与晒码互动游戏赢“83行代码”T恤！

我们来说说这群女工程师的第83行代码及代码背后的故事：

清宵：人生如码

我是阿里云函数计算团队技术专家清宵，用动图撩一下大家吧~~大家好！

我的第83行代码来自这个简单的Life模型，非项目非社区贡献，纯业余时间自娱自乐。
看了《药神》之后，对人生的感悟加深。回来没有写什么观后感，却是随便写了一段代码，构造一个极其简单的人生模型，算作总结思考了。
人生如码，以梦为马。珍惜所爱，精彩过好每一天！
